Soon we will be able to replace fossil fuels with a carbon-neutral product created from solar energy, carbon dioxide and water. Researchers at Uppsala University have successfully produced microorganisms that can efficiently produce the alcohol butanol using carbon dioxide and solar energy, without needing to use solar cells. The results have been published in Energy & Environmental Science.
Bacterial ribosomes need a single-stranded ribosome binding site (RBS) to initiate protein synthesis, whereas stable RNA structure blocks initiation. Paradoxically, structured mRNAs can nevertheless be efficiently translated. Researchers at Uppsala University have now elucidated the anatomy of a "standby" site and its requirements, to overcome RNA structure problems for translation.
The majority of women who undergo surgery for suspected ovarian cancer do not have cancer. A novel blood test developed by researchers at Uppsala University and University of Gothenburg, now offers the possibility of more precise diagnostics. This could lead to a reduction in unnecessary surgery and to earlier detection and treatment for affected women. (Communications Biology).
One key question in evolutionary biology is how novel genes arise and develop. Swedish researchers now show how new genes and functions that are advantageous to bacteria can be selected from random DNA sequences. The results are presented in the scientific journal mBio.
New data from the Uppsala Conflict Data Program (UCDP), Uppsala University shows that in 2018 the number of fatalities in organised violence reached the lowest level in seven years. However, the large share of internationalised conflicts, to which external states contribute troops, worries researchers. These conflicts tend to be both bloodier and longer.
Both infants and their parents flexibly several behaviors to establish frequent episodes of joint attention. A new study shows that infants who are later diagnosed with autism seldom actively seek to establish such episodes themselves. This finding provides support for the view that children with autism have reduced social motivation already as infants.
A team of Swedish and British scientists have studied the heritability of dog ownership using information from 35,035 twin pairs from the Swedish Twin Registry. The results indicate that an individual’s genetic make-up has a great influence on whether they choose to acquire a dog. Genes appear to account for more than half of the difference in dog ownership.
Nearly ninety per cent of all cancer patient deaths are due to metastasis. A study from Uppsala University shows that a process that allows the cells to metastasise is aided by the synthesis of new ribosomes, the cell components in which proteins are produced. The results open the possibility for new treatment strategies for advanced cancers. The study is published in Nature Communications.
A research project led by Uppsala University has been awarded a EUR 3.2 million grant by the European Commission. The aim is to create renewable solar fuel using soap foam, carbon dioxide and sunlight.
For the first time, researchers have demonstrated the creation of a beam of nanodroplets capable of delivering a variety of biological samples, from cell organelles to single proteins, virtually free from any contaminations, to the focus of an X-ray laser which can be used to image them.
By 2050, around 70 per cent of the world’s children will live in cities. During the high-level meeting Uppsala Health Summit this autumn, international experts from different sectors will gather to discuss how to plan cities and strengthen public health strategies to better care for children’s health and wellbeing in all parts of the world.
High levels of polychlorinated biphenyls (PCBs) in the blood are associated with premature death. This is shown by a cross-disciplinary study, based on 1,000 randomly selected 70-year-olds in Uppsala, that is published in the JAMA Network Open journal today.
Founded in 1477, Uppsala University is the oldest university in Sweden. With more than 50,000 students and 7,500 employees in Uppsala and Visby, we are a broad university with research in social sciences, humanities, technology, natural sciences, medicine and pharmacology. Our mission is to conduct education and research of the highest quality and relevance to society on a long-term basis. Uppsala University is regularly ranked among the world’s top universities.
